Aristolochia spp

Aristolochic acid derivatives have been found only among plants of the family Aristolochiaceae (Aristolochia spp. and Asarum canadense var. reflexum (34)) and in Bragantia wallichii (35,36). In all derivatives, substitution of nitro group is present at C-10, the carboxy group is present at C-1, and a methylenedioxy is substituted at C-3 and C-4 only. This general structure will be very interesting in biosynthesis and plant biochemistry. 

Negative results were obtained for Aristolochia hurchellii, A. didyma, A. jaliscana, A. kankauensis, A. macrophylla, A. paulis-tana, Aristolochia spp. (3), A. triangularis, Asarum canadense, A. lemon ii, A. lailoense.
